Windows 7: Could not change task parameters programmtically!

Could not change task parameters programmtically!


I have a peculiar issue with task scheduler in win7. I have programatically added a task specifying certain parameters ( set the parameters using ITask::SetParameters ()). Then I modified the parameters again with new value.When I changed the parameters using ITask::SetParameters (), It returns S_OK, I save it using IPersistFile::Save(). It is also returning S_OK.

But, when I open 'Task Scheduler', I see the task is still holding the old parameters!!.

I am confused with this behavior. This problem does not happen with Windows XP.

Need your help.

ITask::SetParameters Method (Windows)

looking at the documentation, it mentions:
To clear the command-line parameter property, set pwszParameters to L"".
is there a typo there? Anyway, do you need to clear the params first? Perhaps you can clear them, then check - if not... i'm thinking permissions issue on file write?... but it returns S_OK... hmm...

find solution ?

Hi, did you find a solution ?

I'm in the same case. If i create a task from the task scheduler API 1.0, the task exists and works but doesn't appear in the task scheduler control panel.
